#Samsung Finally Has a Phone That Runs Its Own Operating system After years of delays and false starts,
Samsung Electronics Co. has launched finally a smartphone that runs on its own Tizen operating system, a landmark move that may mark the beginning of the end of its dependence on Google Inc. Android system.
In truth, Samsung had been left with little alternative after three failed launches last year frustrated the developers that it needs

Samsung was deposed last year by Xiaomi as the largest smartphone maker in China. Tizen is already in use in Samsung smartwatches and cameras and, most recently, its TVS.
The company ultimately intends to make it the cornerstone of its strategy for making all of its household appliances connectable to the nternet of Thingsin due course.
even in the world third biggest market for smartphones, Samsung can achieve enough scale for Tizen to persuade skeptical developers that making apps for it is worth their while.
